BUTTONHOLE AND METHOD OF MAKING THE SAME.

To all whom it may concern:

Be it known that I, MICHAEL MOCANN, a citizen of the United States ofAmerica, residing in 'Glenmorris, Long Island, in the county of Queensand State of New York, have invented certain new and useful Im-.provements in Buttonholes and Methods'of Making the Same. of which thefollowing is 1 a true and exact description,- reference being had to theaccompanying drawings, which form a part thereof.

My invention relates to the formation of a stitched button hole and hasfor its object to provide a button hole which, by reason of theformation and co-relation of its formative stitches. will be stronger,better looking and, in the direction of its length, less extensible thanhas heretofore been the case with stitched button holes. The essentialnovel feature of my new button hole and of my new method lies in theformation of two lines of straight stitches said lines running parallelto each other on each side of the button hole and the formation overthese straight lines of stitches of two lines of zig .zag stitches suchas are usually formed by button hole sewing machines. By preference Ialso form barring stitches at each end of the button hole and in theusual manner.

The function of the straight lines of stitches in my new button hole istwo fold; first, these straight lines of stitches, being comparativelyinextensible, prevent the longitudinal stretching of the button holewhich is important; with stretchable knitted or woven goods, and second,these lines of stitches serve as padding stitches for the overlying zigzag lines of stitches giving them an attractive rounded contour.

In the drawing which illustrates my invention- Figure 1 is a somewhatdiagrammatic face view of my new button hole.

Figure 2 is a face or plan view showing the two lines of straightstitches and a series of barring stitches at one end of the lines ofstraight stitches.

Figu the goods taken on one line of straight stitches, a needle andlooper being also shown as co-operating to form the stitches in the formof looped stitches, and

re 3 is a sectional elevation through Figure is a view similar to Fig.2, showing a portion of the straight lines of stitches as overlaid byzig zag stitches.

A indicates the goods in which the button hole is formed. B, Fig. 3, isaneedle end, C a co-operating looper andD a thread used in stitching thebutton hole but it will be understood that any type of sewing machinemay be used in stitching my button hole which can as well be formed oflock stitches as of loop stitches. E, E, etc. and e, 6, etc., are twoparallel lines of straight stitches, one formed on each side of thebutton hole to be formed. F and f are barring stitches formed at one endof the stitches E and e. (l and g are zig zag stitches formed over thestraight stitch lines E and e, and H, h, are barring stitches formed atthe finish end of the button hole.

My button hole can be formed on any type of button hole sewing machineorganized to form zig zag stitches by organizing such a machine to'formthe two lines of straight stitches preliminary to the ordinary zig zagH, h, maiy be formed first then the straight stitches 6, then thebarring stitches F, f, and finally the zig zag stitches G, g.

In my pending application filed Sept. 23, 1919, Serial No. 325,710 Ihave described a machine especially adapted to form my new button holebut the button hole can be made in any way, even by hand, and I do notwish my claims to' be understood to be limited to a machine made buttonhole.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. -As a new article of manufacture a button hole having two parallellines of straight stitches extending from end to end of the button holeone on each side thereof and two lines of zig zag stitches formed overthe straight stitches.

2. As a new article of manufacture a button hole having two parallellines of straight stitches extending from end to end of the button holeone on each side thereof, two lines of zig zag stitches formed over thestraight stitches and barring stitches formed at the ends of the buttonhole.

3. The method of forming a button hole which consists in forming twoparallel lines of straight stitches extending from end to of straightstitches extending from end to end of the button hole one on each side 1end of the button hole one on each side thereof, forming barringstitches at each end thereof and subsequentl 1 forming over each of saidlines of stitches and forming a series a of said straight lines 0stitches a series of of zig zag stitches over each line of straight zigz%]stitches. stitches.
